Are all treatments approaches equally effective?

Bruce Wampold, Ph.D.

Late yesterday, I blogged about a soon-to-be published article in Clinical Psychology Review in which the authors argue that the finding by Benish, Imel, & Wamppold (2008) of equivalence in outcomes among treatments for PTSD was due to, “bias, over-generalization, lack of transparency, and poor judgement.” Which interpretation of the evidence is correct? Are there “specific approaches for specific disorders” that are demonstrably more effective than others? Or does the available evidence show all approaches intended to be therapeutic to be equally effective?

History makes clear that science produces results in advance of understanding. Until the response to Ehlers, Bisson, Clark, Creamer, Pilling, Richards, Schnurr, Turner, and Yule becomes available, I wanted to remind people of three prior blog posts that review the evidence regarding differential efficacy of competing therapeutic approaches. The first (and I think most illuminating)–“The Debate of the Century“–appeared back in August. The post featured a link to a debate between Bruce Wampold and enthusiastic proponent of “empirically supported treatments,” Steve Hollon. Listen and then see if you agree with the large group of scientists and practitioners in attendance who thought–by a margin of 15:1–that Bruce carried the day.

The second post–Whoa Nellie!– commented on a 25 Million US$ research grant awarded by the US Department of Defense to study treatments for PTSD. Why does this make me think of “deep throat’s” admonition to, “follow the money!” Here you can read the study that is causing the uproar within the “specific treatments for specific disorders” gang.

Third, and finally, if you haven’t already read the post “Common versus Specific Factors and the Future of Psychotherapy,” I believe you’ll find the thorough review of the research done in response to an article by Siev and Chambless critical of the “dodo verdict” helpful.

DODO BIRD HYPOTHESIS PROVEN FALSE! Study of PTSD finally proves Wampold, Miller, and other "common factor" proponents wrong

Researchers Anke Ehlers, Jonathon Bisson, David Clark, Mark Creamer, Steven Pilling, David Richards, Paula Schnurr, Stuart Turner, and William Yule have finally done it! They slayed the “dodo.” Not the real bird of course–that beast has been extinct since the mid to late 17th century but rather the “dodo bird” conjecture first articulated by Saul Rozenzweig, Ph.D. in 1936. The idea that all treatment approaches work about equally well has dogged the field–and driven proponents of “specific treatments for specific disorders” positively mad. In a soon to be published article in Clinical Psychology Review, the authors claim that bias, overgeneralization, lack of transparency, and poor judgement account for the finding that “all therapeutic approaches work equally well for people with a diagnosis of PTSD” reported in a meta-analysis by Benish, Imel, & Wampold (2008).

I guess this means that a public admission by me, Wampold, and other common factors researchers is in order…or maybe not! Right now, we are writing a response to the article. All I can say at this point is, “unbelievable!” As soon as it becomes available, you’ll find it right here on this blog. I’ll be drawing inspiration from Saul Rosenzweig who passed away in 2004. It was such an honor to meet him. Still working at 96 years of age.

Why ongoing, formal feedback is critical for improving outcomes in healthcare

Not long ago, I had a rather lengthy email exchange with a well-known, high profile psychotherapist in the United States. Feedback was the topic. We both agreed that feedback was central to successful psychotherapy. We differed, however, in terms of method. I argued for the use of simple, standardized measures of progress and alliance (e.g., ORS and SRS). In support of my opinion, I pointed to several randomized clinical trials documenting the impact of routine outcome monitoring on retention and progress. I also cited studies showing traditionally low correlations between consumers and clinician’s rating of outcome and alliance and clinicians frighteningly frequent inability to predict deterioration and drop out in treatment. He responded that such measures were an “unnecessary intrusion,” indicating that he’d always sought feedback from his clients albeit on an “informal basis.” television-reception

When I mentioned our own research which had found that clinicians believed they asked consumers for feedback more often than they actually did, he finally seemed to agree with me. “Of course,” he said immediately–but then he added, “I don’t need to ask in order to get feedback.” In response to my query about how he managed to get feedback without asking, he responded (without a hint of irony), “I have unconditional empathic reception.” Needless to say, the conversation ended there.

It’s a simple idea, feedback. Yet, as I jet around the globe teaching about feedback-informed clinical practice, I’m struck by how hard it seems for many in healthcare to adopt. Whatever the reason for the resistance–fear, hubris, or inertia–the failure to seek out valid and reliable feedback is a conceit that the field can no longer afford. Simply stated, no one has “unconditional empathic reception.” As the video below makes clear, we all need help seeing what is right before our eyes.
